    - NumericUpDown ValueChanged Hi, I'm using a numericupdown in my app. The event ValueChanged fires when the value is changed via the up down arrows. However, if I change the value by editing the text directly, this event does not fire until I change focus to another control. Is it possible to disable the user from entering a value directly into the numericupdown, and just confien them to using the up down arrows to change the value? Thanks again for any tips.

    - PocketPC System DLL problem Hi, I am new to PocketPC development. Using VS2008 targeting the 3.5 FrameWork. I have a third party DLL that I have referenced successfully in a Windows app project When I declare an object from the DLL in my PocketPC project I get the following when building. Error 1 The type 'System.ComponentModel.Component' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. C:\ProjectsWorking\Coronis\PocketPC\CoronisPocketPC\CoronisPocketPC\Form1.cs 13 26 CoronisPocketPC Does this mean that the third party DLL is referencing another version of the System dll? Is there a fix for this? Thanks Bob Tag: Send keystroke to edit control Windows CE / .NET Compact Framework Tag: 87434

    - Hardware Keys in Windows Mobile 6 With previous versions of Windows Pocket PC I have been using the code below, but now I switched to a iPAQ 114 using Windows Mobile 6 and it doesn't work any more. Anyone has an idea what could be wrong ??? Why isn't it possible to override hardware keys in Windows Mobile 6 with "RegisterHotKey" ??? I have have the situation where when the hardware keys are pressed they do what I want them to do BUT also still open the calendar, contacts and inbox applications in addition - which is what I don't want them to do. So I think there must be some problem with the UnregisterFunc1, but I really don't know.

    - NotSupportedException on Windows Mobile Device ... Hi Everyone, I am writing a simple application to start with Windows Mobile 6. Though, I have developed many applications on .NET Framework 1.1, but this is the first time I am working on Compact Framework. I have tried to write an application, that creates a simple form with 2 buttons on that, "Hide" and "Unload". I built the application well and copied it to the device. The application was build using FW 3.5 and before running the application on the device, I installed .NET CF 3.5 (NETCFv35.wm.armv4i.cab) on the device and rebooted it. When I run the application, it fails during the execution of method "InitializeComponent()". The error is below: SmartDeviceApplication1.exe NotSupportedException at Microsoft.AGL.Common.MISC.HandleAr(PAL_ERROR ar) at System.Windows.Forms.Controls._InitInstance(WNT wnt, UInt32 dwStyle) at System.Windows.Forms.Control..ctr(WNT wnt) at System.Windows.Forms.Button..ctr() at SmartDeviceApplication1.Form1.InitializeComponent() at SmartDeviceApplication1.Form1..ctor() at SmartDeviceApplication1.Form1.Program.Main() I have only set the text property of the buttons, no tricky code, no functionality ... I am not clear what is not supported, The button control or the Framework ? OR is it a symptom of some other problem. Not that this application works well on the Classic device Emulator. Can some one knows about it ? Thanks, *(Vipul)() ; Tag: Send keystroke to edit control Windows CE / .NET Compact Framework Tag: 87420

    - Can .Net CF do real time I/O and comm? Our company is evaluating new technologies for a new product. I am a big fan of using widely supported, easy to use, off the shelf technology as much as possible. The application involved uses industrial I/O. I, personally, would prefer to program in C# with an integrated debugger, but some of my colleagues insist that the .Net Compact Framework is totally unsuited to the task, because it is "not real time". If they win, we have to end up developing in C on some sort of embedded development package, which seems to me a big step down. The application involves digital I/O in a machine on a factory floor. The application will receive a message on the Ethernet port. Within 2 milliseconds, it must set the digital I/O bit, turning off the motor it is controlling. After that, it is guaranteed that nothing important will happen for the next 500 milliseconds. It seemed to me that the .NET compact framework is well suited to the task because the only non real time aspect is garbage collection. We can run the task, get the message, set the bit, and force a garbage collection after we are done, during the 500 millisecond idle time. That way, we will never end up with a GC that interrupts anything important. My colleagues are not sold on this idea. They have read that it is "not real time", and that is that. Can anyone offer supporting examples of using the .NET Compact (or even Micro) framework on such a task? Tag: Send keystroke to edit control Windows CE / .NET Compact Framework Tag: 87419

    - MessageQueue.Send error 0x80004005 Hi all, We have a .NET application running on a Windows CE 5.0 device based on Intel IXP425 (ARM) processor. This application works properly doing periodic transmissions to a MessageQueue until one of those transmissions fails. The MessageQueue.Send() instruction returns a MessageQueueException with exception error code=3D -2147467259 (0x80004005). The queue condition at this moment seems to be ok and up to this moment the application has done more than 10000 sending operations without any problem. The error doesn=B4t seem to occur in a systematic way. Sometimes it can take 15 days to occur and in other cases it can occur within the first 2 hours. The messages sent to this queue all this time are identical or very similar to each other. We would appreciate any information or suggestions. Thanks in advance!

    - Map Control Hello, Can anybody recommend a .NET Compact Framework control to display a roadmap in a mobile app, similar to Google Maps? Free or commercial is OK. I have looked quite a bit, but have only found a few options, and they all have some issues. I was surprised; it seems like this would be a common control to want, and I expected the big mapping providers to have a high-quality drop-in GUI component for sale, but they didn't seem to.

    - Launching instant messenger Hello, I'm wondering if there's a way to programatically launch a user's mobile instant messaging client. We have a list of users and their contact information, including IM providers and usernames, and we'd like to provide links to start sending an IM to those users, as we currently do to call them or send them email. On the desktop with AOL Instant Messenger installed I can launch an "aim:" URL to bring up AIM and start sending a message to a particular user. ICQ supports a similar protocol, as does Google Talk. On Windows Mobile, I can launch a "mailto:" link to start sending a message, or use the telephony API to start a call to somebody, but "aim:" and other protocols don't seem to be registered. Is there a somewhat standard way to find out if a user has an IM client for a particular service installed and tell it to start a message to another user? If not, does anybody happen to know tricks to do this with some of the more common mobile IM clients? Thanks for any thoughts! ----Scott.

    - Message constant values or magic numbers? (C#) I didn't find any namespace for some Windows constants when I working in .NET CF and C# (e.g. WM_PAINT or any other message constants). I can use direct values of these message-constants but I don't like use any "magic number" in my source codes. It would be better if I used a namespace-constant (e.g. System.Windows.Forms.MessageValue.WM_PAINT or somethink like this). I can create this namespace but I think that it should exists in .NET Compact Framework library. Using values from standard windows.h (winuser.h) header file can make a mistake because some constants in CE differ from constants in other Windows versions (e.g. see WH_KEYBOARD_LL windows hook message). The questions are: 1. Are there any namespaces to enumerate these constant values? 2. If not, how can I find a correct values for Windows messages instead of using "magic numbers"?

    - Panel I am having issues with SelectNextControl when there is a panel that contains multiple controls that have tab stops. I played with the tabindex in the editors and things still do not work. So in my constructor of my form I forced tabindex of my panels, but then I get a warning VSD101 saying the method is unsupported. But if I create a temporary control variable then it is fine. Is this a compiler error? // This compiles fine Control tmpCtrl; tmpCtrl = DSetBtnPnl; tmpCtrl.TabIndex = 50; // This gives the following warning //warning VSD101: Members not supported by the device platform should not be called: System.Windows.Forms.Panel.set_TabIndex is not a supported method in this platform ((Control)DSetBtnPnl).TabIndex = 50; Everything runs fine on the device. I figured if I casted the panel to a control, it should treat it as a control. -- Thanks, Juan Tag: Send keystroke to edit control Windows CE / .NET Compact Framework Tag: 87370

    - Accessing files in mobile device programmatically from a PC Hi guys, I have a number of mobile devices which will be connected, one at a time, to a PC. (USB connection + ActiveSync.) I need to run a program (C#) in the host PC that can access each device's memory in turn and exchange files with them. Here's the catch; I'd like to *not* have to run a program from each device as I place it on the cradle, relying instead on the included ActiveSync features. I.e., it should be as easy as placing the next device and pressing a key in the host PC. I'm having trouble getting to the appropriate folder. Using the "Explore" button in ActiveSync gives me the "Mobile Device" folder, from where I can navigate to the appropriate drive -- but I can't get there any other way. If I use an OpenFileDialog it never shows me the device in My Computer, even though Windows Explorer does. Any hints? Thanks in advance! Cheers, Pedro.

    - TimeSpan calculation error Hi, Assuming dt1 and dt0 (DateTime structs) represent times about or less than one second apart, then using: (dt1 - dt0).TotalSeconds (or TotalMilliSeconds, or dt1.Subtract (dt0)) returns 0.0 *or* 1.0 whereas on the desktop, .NET can return any value between 0.0 and 1.0. Is this a known issue? Hilton Tag: Send keystroke to edit control Windows CE / .NET Compact Framework Tag: 87287

    - Failed HttpWebRequest to an HTTPS server takes 100% of CPU We have a CE 5.0 application (.NET CF 2.0) that we use to download files from both secure and non-secure servers over HTTP and HTTPS. When making a request to a misconfigured server over HTTPS, we noticed that the CPU on our device would jump to 100% and stay there indefinately. We traced this to a thread that appears to be created when calling HttpWebRequest.GetResponse(). It appears that when we make a request to this specific server, the TCP connection gets established and the client sends its "Client Hello" message to the server. The server immediately closes the connection (you can see the FIN-ACK from the server over Wireshark). Here is where the problem occurs: If you are making this request from a client PC using the full .NET framework, the client completes the handshake by sending its own FIN and the connection is closed. HttpWebRequest.GetResponse() returns immediately with an error stating that the server closed the connection. However, if you are making this request from a CE 5.0 client running the compact framework, the connection never gets closed from the client side. Instead, HttpWebRequest.GetResponse() does not return until the specified timeout expires. In addition to this, even after calling Abort() on the request object, a thread is leftover that seems to spin forever and takes up 100% of the CPU. This does not appear to happen when making non-HTTPS requests, nor when making requests to a properly configured server or a server that is not listening on port 443 at all. I was able to recreate this easily by writing a simple test server that runs on Windows XP (in C++) and test client for CE in C#. The test server listens for a TCP connection on a port, accepts a connection, receives one packet and then closes the socket. The test client simply creates an HttpWebRequest object for the specified server and port and calls GetResponse(). Every time (repeatable on more than one device and more than one computer hosting the server) the call to GetResponse() will result in a spawned thread that eats up the CPU. Again, calling Abort() on the request object does not seem to clean things up. Does anyone have any ideas? I have pasted the code below, but can send the solution files if required. ================================================ SimpleTCPServer (C++ Win32) ================================================ #include <winsock2.h> #include <windows.h> #include <stdio.h> #define LISTEN_PORT 9091 int _tmain (int argc, TCHAR* argv[]) { WSADATA wsaData; SOCKET sock = INVALID_SOCKET; sockaddr_in local; SOCKET client; sockaddr_in from; int fromlen=sizeof(from); char buf[512]; // initialize WinSock if(WSAStartup(MAKEWORD(2,2), &wsaData)) { printf("WSAStartup() failed\r\n"); return 0; } while(true) { // create socket local.sin_family=AF_INET; local.sin_addr.s_addr=INADDR_ANY; local.sin_port=htons((u_short)LISTEN_PORT); sock = socket(AF_INET, SOCK_STREAM, 0); if(sock == INVALID_SOCKET) { printf("socket() failed\r\n"); WSACleanup(); return 0; } // bind if(bind(sock, (sockaddr*)&local, sizeof(local))!=0) { printf("bind() failed\r\n"); closesocket(sock); WSACleanup(); return 0; } //listen if (listen(sock, 5) != 0) { printf("listen() failed\r\n"); closesocket(sock); WSACleanup(); return 0; } // accept the connection printf("Waiting for client to connect on port %d...\r\n", LISTEN_PORT); client = accept(sock, (struct sockaddr*)&from, &fromlen); printf("Accepted TCP connection from %s\r\n", inet_ntoa(from.sin_addr)); // receive the first packet int bytes = recvfrom(client, buf, sizeof(buf), 0, (struct sockaddr*)&from, &fromlen); printf("Received %d bytes from client\r\n", bytes); // close the connection printf("Closing connection\r\n\r\n", bytes); closesocket(client); shutdown(sock, SD_BOTH); closesocket(sock); } WSACleanup(); return 0; } ================================================ SSLClient (CE 5.0, .NET CF 2.0) (just a blank form with a "Send" button on it) ================================================ ... private const string SERVER = "192.168.1.92"; private const int PORT = 9091; private void SendSSLRequest() { HttpWebRequest request = null; HttpWebResponse response = null; try { request = (HttpWebRequest)(WebRequest.Create("https://" + SERVER.ToString() + ":" + PORT.ToString() + "/")); request.Timeout = 5000; request.ReadWriteTimeout = 5000; response = (HttpWebResponse)request.GetResponse(); } catch (Exception ex) { } finally { if (response != null) { response.Close(); response = null; } if (request != null) { request.Abort(); request = null; } } } Tag: Send keystroke to edit control Windows CE / .NET Compact Framework Tag: 87282

    - Enum property of custom control does not appear in VS2005/2008 (C# Hi, I created a .NET CF custom control with a standard type (int) property and a custom one (enum) like this: public enum EnumTest { Value0, Value1, Value2 } When a./ I use an import method using [DllImport()] or b./ I declare any other device-specific field (e.g. field from Microsoft.WindowsCE.Forms.MessageWindow) the enum property of my custom control class does not appear in the Visual Studio property editor. There is not necessary to use the imported method or anything from the MessageWindow field. In addition, there is no error/warning message about VS's problem. Otherwise, the standard typed property (int) appears correctly in this case. My questions are: 1. How can I make visible my custom typed (enum) property in the designer? 2. Enum is not a device-specific part of my control but the VS does not display it. Why? I would appreciate it if anybody would help me. Thanks!

    - Debug a CF application on a PC Hi I know its possible to run a CF application on a normal PC. But is it possible to debug it? I would like to start writting my application on a PC first. Its faster and much easier to debug the functionality on the PC. When I uses a normal projekt it uses the full framework and I have to dobbel check if I have used som function not in the CF. I have added reference to the CF version of System.Windows.Forms, System.* etc instead of those from the full framework. If I then uses some unsupported function I get compile errors. But the problem i, that when I edit the dialog or add new controls, unsupported functionality is added by Visual Studio 2005. If I create a CF projekt, Visual Studio launches an emulator instead and I cant debug on the PC Is it possible to make Visual Studio not launching an emulator when debugging of a CF application? Is it possible to tell VS, just to add/use CF compatible functions on controls? /Thomas Tag: Send keystroke to edit control Windows CE / .NET Compact Framework Tag: 87279

    - How to write IExtenderProvider control for .NET CF? Hi, I searched all over the net and I can't find no info how to do this, other then this post http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=158930&SiteID=1. I would like to rewrite this example http://msdn2.microsoft.com/en-us/library/system.componentmodel.iextenderprovider.aspx for Compact Framework, and I would like to do it VS2005 way. VS2005 suggests to use .xmta file which will produce *.PocketPC.asmmeta.dll file. The article I found also suggests to create yet another library where the designer would be. Does this mean that now instead of distributing two libraries (one for runtime one for design time) I have to distribute three (an extra *.PocketPC.asmmeta.dll)? I have a hard time to believe it. Can anyone shed some information on this? Thank you. Rastio. Tag: Send keystroke to edit control Windows CE / .NET Compact Framework Tag: 87258

    - Memory problem with SqlCeEngine.Compact Hi all, We are having a memory leak, in our application. The problem is that we only can reproduce it 3 times. And we cannot find the pattern of this bug. In our application when the user finishes one special section, an automatically full backup is executed (If the users setup it in this way). Our backup does this: ///close all DReaders, Dcomad's, and connections to de DB SqlCeEngine engine = new SqlCeEngine("Data Source = DB.sdf")); engine.Compact("Data Source='"DBBK.sdf ";"); engine.Dispose(); /// open connection again to the DB.sdf The error we log is this: Error Message: Not enough storage is available to complete this operation. Stack Trace: at System.Data.SqlServerCe.SqlCeEngine.ProcessResults() at System.Data.SqlServerCe.SqlCeEngine.Repair() at System.Data.SqlServerCe.SqlCeEngine.Compact() at Backup.CompactDatabaseBackUp() at Backup.CreateBackUp() at BackUpControl.DoBackUp() We are using CF 2.0, and the bug was reproduce with a 3 MB DB. As I tell you before, this happens occasionally. So I don't know what to do, I call the GC.Collect or GC.WaitForPendingFinalizers always before SqlCeEngine.Compact is call?, or do I have any way to know how memory is at the moment, and if is necessary I call GC.Collect ?

    - Is the TypeConverter attribute supported in CF 2.0? Does anybody know if the TypeConverter attribute is suppored in CF 2.0? I have found an example of a person using it claing to be in the CF world... But I get a compile error that TypeConverter is not an attribute class. MSDN seems to show that it isn't supported which would back up the compiler error. Here is a link to the example that I found: http://groups.google.com/group/microsoft.public.dotnet.framework.compactframework/browse_thread/thread/52fe4d21322edafb/4d3059ecce1ed73d?lnk=gst&q=typeconverter#4d3059ecce1ed73d What I'm trying to do is databind an object without using the Parse and Format methods. In the full framework we have implemented this by creating a class derived from TypeConverter and all of our Business Objects specify this class by using the TypeConverter attribute. Does anybody know how I can convert a string to my Business Object in the business layer (textbox binding). Right now I have to do it in the UI layer using code like this... private void orderNumberBinding_Parse( object sender, ConvertEventArgs e ) { e.Value = new OrderNumber( e.Value as string ); } Any help is appreciated.

Hi,

Because there's not enough room for the inputpanel on one of the
windows of my application that's running under Windows CE on a PDA/
Smartphone, I made a few buttons (I only need 0-9 the comma and a
backspace). When pressing a button certain text is sent to the
selected control.
Unfortunately it's not possible to get the selected text from an edit
control in the .NET Compact Framework, so I actually do not know what
should happen when I press one of the buttons and send a keystroke to
the selected edit field. (Should it replace text, append text, or put
some text inbetween?)

I tried to work around the problem with using keydbd_event, sending
VK_KEY codes. That works perfect!
But.... not on a smartphone with a physical-keyboard on it. Because
when I now send VK_5, it sends the 'J'...

Anyone has experience with this, and how to work around the problem
mentioned?

Thanks.

Marco
